A solution contain three stereoisomers of 2,3-dihydroxy butanedioic acid. On fractional crystallization of this solution, two fractions. Fraction–I and Fraction–II are separated. Fraction-I on reaction with (+)-2-butanamine gives a single salt while Fraction-II on reaction with the same (+)-2-butanamine gives a mixture of two salts. Answer the following three questions based on the above information.
What is the relationship between the molecules of fraction-I with the molecules of fraction-II
- They are enantiomers
- They are identical
- They are diastereomers
- They are diastereomers as well as optically active
Answer
(C) They are diastereomers
